Treaty of Independence, Spartan: Agreement signed between the Grand Senate of the CoDominium and the Dual Monarchy of Sparta (q.v.), 2062. The Constitutionalist Society's original settlement agreement with the Colonial Bureau of the CoDominium had provided for full internal self-government, but the CoDominium retained jurisdiction over a substantial enclave in Sparta City, (q.v.), the orbital transit station Aegis (q.v.), and the refueling facilities around the gas-giant planet Zeus.

Under the terms of the Treaty, the Royal government became fully responsible for internal order and external defense of the Spartan system, and all restrictions on local military and police forces were removed.

Also mandated was the continued receipt of involuntary colonists at a level to be set by the Bureau of Relocation, and for this purpose the CoDominium enclave in Sparta City was retained with a reduced garrison. Penalty provisions in the Treaty authorized direct intervention by the Commandant of the enclave should the Royal government fail to fulfill these obligations…
